Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 24,48,110VDC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 5. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSD-200-12)
- 6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the RSD-200B-48 to power 48V telecom or networking equipment from a low-voltage DC source?
Yes, this model is built for a constant 48V output and can deliver up to 4.2A with a 201.6W rating. Its 16.8 to 31.2VDC continuous input range makes it suitable where a lower-voltage source must be converted to a regulated 48V rail.
Is the RSD-200B-48 suitable for 48V industrial communication devices or edge networking hardware?
It can be used for 48V communication and networking loads that stay within 4.2A and 201.6W. That makes it a practical option for systems needing stable 48V power from a source in the 16.8 to 31.2VDC range.
Can this converter support 48V control equipment in mobile or vibration-prone industrial applications?
It is intended for harsh-duty use, with an operating temperature range of -40°C to +55°C (no derating) and a feature note for withstanding 5G vibration. Those specs support use with 48V control electronics in industrial vehicles or mobile equipment when the load is within 4.2A.
Is the RSD-200B-48 a fit for compact 48V subsystems inside machinery enclosures?
It can be a fit where 48V output is needed up to 4.2A and the available source is 16.8 to 31.2VDC. Its size of 191 × 86 × 40 mm helps in machinery enclosures where power density and space both matter.
How does the RSD-200B-48 compare with the 12V and 24V versions in the same family?
In the RSD-200B series, the 12V model is 200.4W at 16.7A, the 24V model is 201.6W at 8.4A, and the 48V model is 201.6W at 4.2A. They are differentiated by output voltage and corresponding current capacity rather than by major changes in series form factor.
Can the RSD-200B-48 be used in outdoor or temperature-variable environments?
The published operating temperature range is -40°C to +55°C (no derating), extending to +70°C at 60% load by free air convection. No IP rating is listed in the provided specs, so direct exposure to rain, washdown, or dust should be managed by the enclosure rather than assumed from the converter alone.
